The vacancy rate represents the number of positions that are open and actively being recruited. While the radiographer vacancy rate this year was on a par with the 2.1 percent rate reported in the 2010 ASRT survey, the rate has steadily dropped from 10.3 percent as reported in ASRT’s first staffing survey in 2003.

“The steady decline in vacancy rates is a strong indicator that the job market for radiologic technologists continues to be slow,” said Myke Kudlas, the ASRT’s chief academic officer. “The tight market also can be seen in the vacancy rates for other medical imaging disciplines.”

In addition to the dip in vacancy rates for radiographers, the 2011 survey shows that the average number of full-time radiographers per medical imaging facility fell 12.2 percent — from 10.6 in 2010 to 9.3 in 2011.

On the bright side, the average number of full-time CT technologists per facility rose from five in 2010 to 5.6 in 2011. The number of full-time technologists working in magnetic resonance, mammography, nuclear medicine and sonography also rose slightly per facility from 2010 to 2011.

“It’s difficult to pinpoint exactly what’s causing the decline in the number of full-time radiographers,” Kudlas said, “but it might indicate a shift in the percentage of advanced diagnostic imaging procedures that are being performed in facilities.”
